QTextEdit does not show!!!!

Hi again to all!

I have a code:
Code:
void CMerchandizeBrowser::paintEvent(QPaintEvent* event)
{
    Q_UNUSED(event);
    QPainter painter(this);
    painter.setRenderHint(QPainter::Antialiasing, false);
    painter.drawImage(QPoint(0,0), d->buffer);
 
    // shows merchandize info: name, price, descriptions
    painter.setPen(Qt::white);    // sets white pen's color
    painter.setBrush(Qt::NoBrush);    // sets brush
    //p.drawRect(merchandizeDescriptionRect);
    painter.setFont(QFont("Arial", 12));    // sets test font
    QFontMetrics fm(painter.font());    // sets up font metrcis
    QRectF computedRec(merchandizeDescriptionRect);
/*
    painter.drawText(computedRec, Qt::AlignLeft, getMerchandizeName(m_ImagesList.at(m_iSelected).text(strKeyImagePathName)));
*/
    painter.drawText(computedRec, Qt::AlignLeft, getMerchandizeName(d->slideImages.at(currentSlide()).text(strKeyImagePathName)));
    // appends "euro" sing at the end of the price
    QString priceString(getMerchandizePrice(d->slideImages.at(currentSlide()).text(strKeyImagePathName)));
    priceString=priceString.append(" EUR");
    painter.drawText(computedRec, Qt::AlignRight, priceString);
    // shows merchandize description
    QTextEdit merchandizeDescription(getMerchandizeDescription((qint16)currentSlide()), this);    // new instance of qtextedit
    merchandizeDescription.show();    // shows constucted text
}
And QTextEdit is not shown? Can someone help me out, please?
